First the external impression: The power supply is super processed, the plastic makes a high impression, the surface is matt and roughened. The plug in the respective adapter through which the output voltage of the power supply is set to the respective laptop types (laptops from different manufacturers require different voltages for charging) is solid and stable, so it should have a long life. The angled 90 ° connectors are solidly built, through the 90 ° bend, the cable should be less stressed. At least the way I use the laptop ..
What's especially great about this power supply: a USB socket for connecting a mobile phone charging cable is directly integrated into the power supply! Anyone traveling with a laptop, a charger for smartphones has therefore always automatically. Of course, this is very handy on your desk.
Now that I have for a while had no real use for the good piece finally came now the new laptop to my wife, an Acer VN7. On him the power adapter fits even though he is not in the list of supported devices. So here's the target more than fulfilled. This power adapter recharges both laptop and my extremely current Hungry Galaxy S3 on quickly. I could not tell the difference from the original Acer at the charging time of the notebook. I have to say that this PSU for Acer works with limitations. One must, therefore it is securely connected unplugging a tiny out of the socket of the notebook. It also charges the laptop with 20 instead of the original power supply 19V.
So I can recommend the power supply all users of laptops mentioned in the product description fully. With around 40, it is also likely to be a lot cheaper than many original charger.
